  • Benkner, Siegfried; Arbona, Antonio; Berti, Guntram; Chiarini, Alessandro; Dunlop, Robert; Engelbrecht, Gerhard; Frangi Caregnato, Alejandro; Friedrich, Christoph M.; Hanser, Susanne; Hasselmeyer, Peer; Hose, D. Rodney; Iavindrasana, Jimison; Köhler, Martin; Lo Iacono, Luigi; Lonsdale, Guy; Meyer, Rodolphe; Moore, Bob; Rajasekaran, Hariharan; Summers, Paul E.; Wöhrer, Alexander; Wood, Steven (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The increasing volume of data describing human/ndisease processes and the growing complexity of understanding, managing, and sharing such data presents a huge challenge for clinicians and medical researchers. This paper ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We focus on full-rate, fast-decodable space–time block codes (STBCs) for 2 x 2 and 4 x 2 multiple-input multiple-output (MIMO) transmission. We first derive conditions and design criteria for reduced-complexity maximum-likelihood ...
  • Sezginer, Serdar; Sari, Hikmet; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The 2×2 MIMO profiles included in Mobile WiMAX specifications are Alamouti’s space-time code (STC) fortransmit diversity and spatial multiplexing (SM). The former has/nfull diversity and the latter has full rate, but neither ...
  • Serrà Julià, Joan; Kantz, Holger; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Intuitively, music has both predictable and unpredictable components. In this work we assess this qualitative statement in a quantitative way using common time series models fitted to state-of-the-art music descriptors. ...
  • Girardin, Fabien; Vaccari, Andrea; Gerber, Alexander; Biderman, Assaf; Ratti, Carlo (Joint Research Centre of the European Commission, 2009)
    In the past, sensors networks in cities have been limited to fixed sensors, embedded in particular locations, under centralised control. Today, new applications can leverage wireless devices and use them as sensors to ...
  • Sadat Schaffai, Jasmin, 1982-; Martin, Clara D.; Costa, Albert, 1970-; Alario, F.-Xavier (François -Xavier) (Elsevier, 2014)
    A crucial step for understanding how lexical knowledge is represented is to describe the relative similarity of lexical items, and how it influences language processing. Previous studies of the effects of form similarity ...
  • Chicharro Raventós, Daniel; Andrzejak, Ralph Gregor (American Physical Society, 2009)
    To detect directional couplings from time series various measures based on distances in reconstructed state spaces were introduced. These measures can, however, be biased by asymmetries in the dynamics' structure, noise ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Wireless “MIMO” systems, employing multiple transmit and receive antennas, promise a significant increase of channel capacity, while orthogonal frequency-division multiplexing (OFDM) is attracting a good deal of attention ...
  • Ortega-Garcia, Javier; Fierrez, Julian; Alonso-Fernández, Fernando; Galbally, Javier; Freire, Manuel R.; González-Rodríguez, Joaquín; García-Mateo, Carmen; Alba-Castro, José-Luís; González-Agulla, Elisardo; Otero-Muras, Enrique; García-Salicetti, Sonia; Allano, Lorene; Ly-Van, Bao; Dorizzi, Bernadette; Kittler, Josef; Bourlai, Thirimachos; Poh, Norman; Deravi, Farzin; Ng, Ming W.R.; Fairhurst, Michael; Hennebert, Jean; Humm, Andreas; Tistarelli, Massimo; Brodo, Linda; Richiardi, Jonas; Drygajlo, Andrzej; Ganster, Harald; Sukno, Federico Mateo; Pavani, Sri-Kaushik; Frangi Caregnato, Alejandro; Akarun, Lale; Savran, Arman (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    A new multimodal biometric database designed and acquired within the framework of the European BioSecure Network of Excellence is presented. It is comprised of more than 600 individuals acquired simultaneously in three ...
  • Singh, Pankai K.; Marzo, Alberto; Coley, Stuart C.; Berti, Guntram; Bijlenga, Philippe; Lawford, Patricia V.; Villa-Uriol, Maria-Cruz; Rufenacht, Daniel A.; McCormack, Keith M.; Frangi Caregnato, Alejandro; Patel, Umang J.; Hose, D. Rodney (Hindawi, 2009)
    Objective: The importance of hemodynamics in the etiopathogenesis of intracranial aneurysms (IAs) is widely accepted./nComputational fluid dynamics (CFD) is being used increasingly for hemodynamic predictions. However, ...
  • Larrabide, Ignacio, 1978-; Villa-Uriol, Maria-Cruz; Cardenes, Rubén; Pozo Soler, José Ma. (José María); Macho, Juan M.; San Román, Luis; Blasco, Jordi; Vivas, Elio; Marzo, Alberto; Hose, D. Rodney; Frangi Caregnato, Alejandro (American Association of Physicists in Medicine (AAPM), 2011)
    Morphological descriptors are practical and essential biomarkers for diagnosis and/ntreatment selection for intracranial aneurysm management according to the current guidelines/nin use. Nevertheless, relatively little work ...
  • Oubel, E.; Cebral, J.R.; Craene, Mathieu de; Blanc, R.; Blasco, Jordi; Macho, Juan M.; Putman, C.M.; Frangi Caregnato, Alejandro (Institute of Physics (IOP), 2010)
    The quantification of wall motion in cerebral aneurysms is becoming important owing to its potential connection to rupture, and as a way to incorporate the effects of vascular compliance in computational fluid dynamics ...
